Microsoft moves headquarters to Bellevue, Washington

Microsoft became independent of MITS in late 1976, and it continued to develop programming language software for various systems.[27] The company moved from Albuquerque to its new home in Bellevue, Washington on January 1, 1979.[26]
During Microsoft's early years, all employees had broad responsibility for the company's business. Gates oversaw the business details, but continued to write code as well. In the first five years, he personally reviewed every line of code the company shipped, and often rewrote parts of it as he saw fit.

1979: Microsoft headquarters are relocated to Bellevue, Wash., a suburb of Gates’ hometown, Seattle.
